Piston Ring (Rally, P/PX 200), 67.1 for Scooters & Mopeds

Piston Ring for Rally and P/PX 200 Scooters

This piston ring suits Rally and P/PX 200 scooters and provides a dependable seal within the combustion chamber, which helps the engine run as it should. Much like other vintage Vespa scooter parts, it drops in as a direct replacement for the worn original. Swap out rings that have worn down to avoid symptoms such as smoke, excess oil use, and weak compression.

What This Part Does

The piston ring's job is to seal the combustion chamber. Once it starts to wear, you may notice more oil being burned and smoke from the exhaust. Before fitting, confirm that the piston's size and pin dimensions match your cylinder so the ring works properly.
